Hi, I am the maker of CutoutGrid. I built this small offline tool to make the workflow above easier without a subscription. CutoutGrid turns already-transparent static PNGs into a consistent set of centered white-square JPGs. Unify the visible subject size, choose 800/1200/1600/2000 px outputs, and export a ZIP with processing reports. Low-resolution images are not enlarged. Runs locally in desktop Chrome. Free demo: 3 images. Full: 50 images per batch, $19 once. Background removal is not included; opaque PNGs and JPG inputs are unsupported. Try the free demo with your own files before buying. The price is a one-time purchase for the current full version. I used AI coding assistance to build the product. The demo video is a captioned slideshow of real screenshots. I would appreciate feedback on the actual output and ease of use.
